Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human vision depends on light-sensitive neurons that are arranged in the back of the eye on a tissue called the retina. The neurons, called the rods and cones because of their shapes, are not uniformly distributed on the retina. Instead, there is a region in the center of the retina called the macula where cones are densely packed, and especially so in a central sub-region of the macula called the fovea. Outside the fovea there...

We present a protocol to obtain cell-derived matrices rich in extracellular matrix proteins, using macromolecular crowders (MMC). In addition, we present a protocol which incorporates MMC in 3D organotypic skin co-culture generation, which reduces culture time while maintaining maturity of construct.

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Electric machines and power electronics experiments involve electrical currents, voltages, power, and energy quantities that should be handled with extreme diligence and care. These may include three-phase AC voltage (208 V, 230 V, or 480 V), up to 250 V DC voltages, and currents that can reach 10 A. Electrocution occurs when an electrical path is established through the body with very low currents...
FAQs
People in crowds influence one another through visible behavior and shared social cues. Individuals may adjust their movement or response to a perceived threat based on what others appear to be doing. Crowd safety strategies therefore consider both individual reactions and group-level patterns, helping researchers and safety professionals anticipate how behavior can either support orderly movement or contribute to dangerous conditions.
Density affects how easily people can move, interpret conditions, and respond to hazards. As groups become more concentrated or movement becomes restricted, congestion can develop and orderly flow may be harder to maintain. Managing density and regulating movement are therefore linked processes, allowing planners to reduce risky crowd conditions before they interfere with safe circulation.
A perceived threat can alter how individuals respond to one another and to their surroundings. Reactions may contribute to panic, sudden changes in movement, or difficulty using available exits, especially when routes are blocked. Effective planning accounts for these behavioral responses by maintaining communication, anticipating hazards, and coordinating timely action when conditions begin to deteriorate.
Behavioral research examines how individuals influence one another, follow social cues, and respond to perceived threats within a crowd. These mechanisms help explain why movement may remain orderly in one situation but become congested or disorganized in another. Studying them gives safety professionals a basis for designing strategies that address collective behavior rather than focusing only on isolated individuals.
Application begins with anticipating crowd behavior and identifying conditions that could create congestion, panic, or blocked exits. Planners then regulate movement and density, maintain clear communication, and establish coordination for timely responses to hazards. This organized approach connects behavioral expectations with practical risk management, supporting safer conditions during gatherings without abandoning orderly movement.
They are especially useful wherever people gather in dense or dynamic groups, including venues and organized events. In these settings, planners can apply behavioral knowledge to improve venue design, anticipate movement problems, and prepare responses to emerging hazards. The strategies also support emergency planning by linking crowd conditions, communication, and coordinated action to safer outcomes.
Crowd safety planning can provide a practical context for examining how people influence one another and react to perceived threats. It also helps connect behavioral observations with outcomes such as orderly movement, congestion, panic, or blocked exits. These findings can inform safer venue design and emergency planning while helping professionals reduce dangerous crowd conditions.
